Information processing system, information processing apparatus, storage medium and information processing method

ABSTRACT

An example of an information processing system is configured to, in a draw mode, display two or more selection candidates. In the draw mode, when a selection instruction to select at least one of unselected selection candidates is given, a game character that corresponds to the selected selection candidate is granted to the user. When the number of unselected selection candidates is equal to a first number, the process decreases an amount by which the predetermined parameter is decreased as compared with a case where the number of unselected selection candidates is equal to a second number greater than the first number. When a cumulative grant count becomes equal to or greater than a reference count, the information processing system permits execution of a designated mode in which a game character designated by the user is granted to the user.

This application claims priority to Japanese Patent Application No.2020-066710, filed on Apr. 2, 2020, the entire contents of which areincorporated herein by reference.

FIELD

The present disclosure relates to an information processing system, aninformation processing apparatus, a storage medium and an informationprocessing method for granting game characters to the user by a draw.

BACKGROUND AND SUMMARY

There are conventional processes in which game characters are granted tothe user by a draw.

Where game characters are granted by a draw, it is preferred to givemore choices to the user as to strategies that can be employed by theuser.

Therefore, the present application discloses an information processingsystem, an information processing apparatus, a storage medium and aninformation processing method, with which it is possible to increase thevariety of strategies for a draw that can be employed by the user.

(1) An example of an information processing system, comprising: aprocessor and a memory coupled thereto, the processor being configuredto control the information processing system to at least: start a drawmode in response to a first start instruction given by a user; in thedraw mode, display on a display device two or more selection candidatesdetermined based on a computer-simulated draw and each corresponding toa game character used in a game, in such a manner that the user canidentify a part of a property of the game characters corresponding tothe selection candidates; in the draw mode, perform a first grantprocess, wherein when the user gives a selection instruction to selectat least one of unselected selection candidates in a state in whichthere are unselected selection candidates, the selected selectioncandidate is indicated as selected and a game character that correspondsto the selected selection candidate is granted to the user in exchangefor decreasing a predetermined parameter; and in the draw mode, end thedraw mode when an end instruction is given by the user or there is nounselected selection candidate left. When a new iteration of the drawmode is started in response to the first start instruction after thedraw mode is ended, the processor displays on the display device a newset of selection candidates that are determined by a newcomputer-simulated draw in the iteration of the draw mode. When theselection instruction is received in such a state in which the number ofunselected selection candidates is equal to a first number, theprocessor decreases an amount by which the predetermined parameter isdecreased for the selection instruction as compared with that in a statein which the number of unselected selection candidates is equal to asecond number greater than the first number. The processor beingconfigured to further control the information processing system to atleast: update a cumulative grant count each time the first grant processis performed in one or more iteration of the draw mode started inresponse to the first start instruction; permit execution of adesignated mode when the cumulative grant count becomes equal to orgreater than a first reference count; start the designated mode inresponse to a second start instruction given by the user; in thedesignated mode, display on the display device one or more of the gamecharacters in such a manner that the user can uniquely identify the gamecharacters; and in the designated mode, perform a second grant processof granting to the user a game character designated by the user.

With configuration (1) above, in the draw mode, the user can employ astrategy of keeping selecting only those selection candidates thatindicate a part of the property of a game character or game charactersdesired by the user, or a strategy of keeping selecting any selectioncandidates displayed as much as possible so as to quickly increase thecumulative grant count in order to execute the designated mode. Thus, itis possible to increase the variety of strategies for acomputer-simulated draw that can be employed by the user.

(2) In the draw mode, the processor may display on the display deviceselection candidates corresponding to a set of game characters that arechosen by a probability-based computer-simulated draw from among aplurality of game characters including normal characters and rarecharacters, wherein a probability of a rare character being determinedas a selection candidate is lower than a probability of a normalcharacter being determined as a selection candidate. In the designatedmode, the processor may display on the display device a rare characteror rare characters as the one or more game characters.

With configuration (2) above, it is possible to strongly motivate theuser to perform the draw mode until execution of the designated mode ispermitted.

(3) In the draw mode, the processor may display on the display devicethe selection candidates corresponding to a set of game characters thatare determined by a probability-based computer-simulated draw from amonga plurality of game characters including normal characters and rarecharacters, wherein a probability of a rare character being chosen as aselection candidate is lower than a probability of a normal characterbeing chosen as a selection candidate. The processor may further controlthe information processing system to at least update a successive grantcount each time a normal character is granted successively by the firstgrant process in the draw mode, and reset the successive grant countwhen a rare character is granted by the first grant process. In the drawmode, on a condition that the successive grant count becomes equal to orgreater than a second reference count, the processor may display on thedisplay device a predetermined number of selection candidates thatcorrespond to rare characters.

With configuration (3) above, it is possible to motivate the user tocontinuously perform the draw mode until the successive grant countbecomes equal to or greater than the second reference count.

(4) In the draw mode, the processor may display on the display devicethe selection candidates corresponding to a set of game characters thatare chosen by a probability-based computer-simulated draw from among aplurality of game characters including normal characters and rarecharacters, wherein a probability of a rare character being determinedas a selection candidate is lower than a probability of a normalcharacter being determined as a selection candidate. The processor maybe configured to further control the information processing system to atleast: update a successive grant count each time a normal character isgranted successively by the first grant process in the draw mode, andreset the successive grant count when a rare character is granted by thefirst grant process; and increase a probability of a rare characterbeing determined as a selection candidate in the draw mode when thesuccessive grant count becomes equal to a third reference count, andreset the probability when the successive grant count is reset.

With configuration (4) above, it is possible to motivate the user tocontinuously perform the draw mode.

(5) The processor, when a rare character is granted by the second grantprocess in the designated mode in a state in which the probability isincreased, may maintain the increased probability.

With configuration (5) above, it is possible to reduce the possibilityof the user losing motivation to perform the draw mode after the end ofthe designated mode.

(6) The processor may prohibit starting a new iteration of the draw modeand permit execution of the designated mode when the cumulative grantcount becomes equal to or greater than the reference count. In the drawmode, the processor may accept a selection instruction until the endprocess is performed even after the cumulative grant count becomes equalto or greater than the reference count.

With configuration (6) above, when the cumulative grant count becomesequal to or greater than the reference count, the information processingsystem prohibits starting a new iteration of the draw mode whileaccepting a selection instruction until the end process is performed.Therefore, when the cumulative grant count becomes equal to or greaterthan the reference count, the user can choose between ending the drawmode immediately and continuing the selection instruction. Thus, it ispossible to increase the variety of strategies for a computer-simulateddraw that can be employed by the user.

(7) The one or more game characters displayed in the designated mode maybe game characters that can be determined as selection candidates by thecomputer-simulated draw in the draw mode.

With configuration (7) above, it is possible to more strongly motivatethe user to perform the draw mode.

(8) Under certain conditions, the processor may accept a selectioninstruction not in exchange for decreasing the predetermined parameterand grants a game character corresponding to the selection candidateselected by the selection instruction to the user. The processor maycalculate the cumulative grant count as a sum between the number oftimes a game character is granted by the first grant process and thenumber of times a game character is granted by the selection instructionthat is accepted not in exchange for decreasing the predeterminedparameter.

With configuration (8) above, the cumulative grant count is calculatedbased on both selection instructions that are given in exchange fordecreasing the predetermined parameter and selection instructions thatare given not in exchange for decreasing the predetermined parameter. Byusing different methods of incrementing the cumulative grant count, itis possible to improve the strategic aspect.

(9) In the information processing system, different draw modes can beexecuted, between which a draw probability is varied for at least onegame character. The processor may update the cumulative grant count forat least one of the draw modes, and update the cumulative grant countfor each draw mode.

With configuration (9) above, it is possible to allow the user to give aconsideration as to which one of a plurality of draw modes to perform,thus improving the strategic aspect of the draw mode.

(10) The processor may accept the first start instruction within apredetermined period in real time. The processor may accepts the secondstart instruction within the predetermined period.

With configuration (10) above, even when the period in which thedesignated mode can be executed is predefined, it is possible to promptthe user to immediately perform the designated mode.

(11) In the designated mode, the processor may grant to the user a gamecharacter designated by the user not in exchange for decreasing thepredetermined parameter.

With configuration (11) above, it is possible to strongly motivate theuser to perform the draw mode until execution of the designated mode ispermitted.

(12) The processor may permit execution of the designated mode until thenumber of times the designated mode is executed becomes equal to apredetermined upper limit number of times.

With configuration (12) above, it is possible to reduce the possibilityof lowering the playability of the draw mode.

(13) The predetermined parameter may represent an amount of virtualcurrency or virtual items in the game.

With configuration (13) above, the user makes a selection in the drawmode in exchange for consuming virtual currency or virtual items in thegame, thus improving the strategic aspect of the computer-simulated drawgame.

Note that the present specification discloses an information processingapparatus (e.g., a terminal apparatus or a server) that executes some orall of the processes recited in (1) to (13) above. The presentspecification also discloses a storage medium storing an informationprocessing program that causes a computer to execute some or all of theprocesses recited in (1) to (13) above. The present specification alsodiscloses an information processing method that is executed by theinformation processing system of (1) to (13) above.

With the information processing system, the information processingapparatus, the storage medium or the information processing method setforth above, it is possible to increase the variety of strategies thatcan be employed by the user in a computer-simulated draw.

These and other objects, features, aspects and advantages of the presentinvention will become more apparent from the following detaileddescription of the present invention when taken in conjunction with theaccompanying drawings.

DETAILED DESCRIPTION OF NON-LIMITING EXAMPLE EMBODIMENTS

[1. Configuration of Information Processing System]

Hereinafter, an information processing system, an information processingprogram, and an information processing method according to the presentembodiment will be described. Firstly, description will be given of theoverall configuration of the information processing system and theconfigurations of the terminal apparatus and a server included in theinformation processing system according to the present embodiment. FIG.1 is a block diagram showing an example of the configuration of theinformation processing system according to the present embodiment. Asshown in FIG. 1, the information processing system includes a server 1and a terminal apparatus 2. The server 1 and the terminal apparatus 2are connectable to a network 3, such as the Internet and/or a mobilecommunication network. The server 1 and the terminal apparatus 2 arecommunicable with each other via the network 3.

The server 1 is a server for providing services related to anapplication (specifically, a game application) to be executed in theterminal apparatus 2. In the present embodiment, the server 1 is a gameserver for a game to be executed in the terminal apparatus 2, andprovides an environment for a game process to be executed in theterminal apparatus 2. For example, in response to a request from theterminal apparatus 2 that executes the game process, the server 1executes a game process according to need, and transmits, to theterminal apparatus 2, data complying with the request (refer to FIG. 1).

The terminal apparatus 2 is an example of an information processingapparatus possessed by a user. Examples of the terminal apparatus 2include a smart phone, a hand-held or stationary game apparatus, amobile phone, a tablet terminal, a personal computer, and a wearableterminal. The terminal apparatus 2 is able to execute a game program (inother words, a game application) for a game for which the server 1provides services.

(Specific Example of Configuration of Server 1)

FIG. 2 is a block diagram showing an example of the configuration of theserver 1. In FIG. 2, each of components included in the server 1 isimplemented by one or more information processing apparatuses. In thisspecification, the “server” means one information processing apparatus(i.e., a server apparatus). When the function of the server isimplemented by a plurality of server apparatuses, the “server” means theentirety of a server apparatus group (i.e., a server system). That is,the “server” may be a server apparatus or a server system. When aplurality of information processing apparatuses are included in theserver system, these information processing apparatuses may be arrangedin the same place or different places. The hardware configuration of theserver 1 of the present embodiment may be the same as that for aconventional server.

As shown in FIG. 2, the server 1 includes a processing section 11 and astorage section 12. The processing section 11 is electrically connectedto the components 12 to 15 of the server 1. The processing section 11includes a CPU (Central Processing Unit, in other words, a processor)and a memory. In the server 1, the CPU executes, using the memory,programs stored in the storage section 12, thereby executing variouskinds of information processing. The storage section 12 is any storagedevice (also referred to as “storage medium”) that is accessible to theprocessing section 11. The storage section 12 stores therein programs tobe executed in the processing section 11, data to be used forinformation processing by the processing section 11, data obtainedthrough the information processing, etc. In the present embodiment, thestorage section 12 stores therein at least a program for a game processthat is to be executed on the server side for a game process to beexecuted in the terminal apparatus 2.

The server 1 includes a communication section 13. The communicationsection 13 is connected to the network 3, and has a function ofcommunicating with other devices (e.g., the terminal apparatus 2) viathe network 3. Using the communication section 13, the processingsection 11 transmits information to the other devices and receivesinformation from the other devices. The server 1 further includes aninput section 14 and a display section 15 as input/output interfaces.

(Specific Example of Configuration of Terminal Apparatus 2)

FIG. 3 is a block diagram showing an example of the configuration of theterminal apparatus 2. As shown in FIG. 3, the terminal apparatus 2includes a processing section 21 and a storage section 22. Theprocessing section 21 is electrically connected to the components 22 to25 of the terminal apparatus 2. The processing section 21 includes a CPU(in other words, a processor) and a memory. In the terminal apparatus 2,the CPU executes, using the memory, a program (specifically, a gameprogram) stored in the storage section 22, thereby executing variouskinds of information processing. The storage section 22 stores thereinprograms to be executed in the processing section 21, data to be usedfor information processing by the processing section 21, data obtainedthrough the information processing, etc. The storage section 22 may be astorage medium incorporated in a main body unit (specifically, a unit inwhich the processing section 21 is provided) of the terminal apparatus2, or may be a storage medium (e.g., a card type storage medium)attachable/detachable with respect to the main body unit. The programmay be stored in the main body unit by being downloaded from the server1 to the terminal apparatus 2.

The terminal apparatus 2 includes an input section 23. The input section23 outputs data based on an input performed by the user to theprocessing section 21. The processing section 21 determines the contentof an input performed by the user based on data from the input section23. The input section 23 may be any input device that receives an inputperformed by the user. In the present embodiment, the input section 23includes a touch panel provided on a screen of a display section 24described later. The input section 23 may include buttons and/or aninertial sensor (e.g., an acceleration sensor or a gyro sensor), etc.,in addition to (or instead of) the touch panel. The input section 23 maybe an input device provided in the main body unit of the terminalapparatus 2, or may be an input device (e.g., a game controller)separated from the main body unit.

The terminal apparatus 2 includes a display section 24. The displaysection 24 displays an image (e.g., a game image, etc.) that isgenerated through information processing executed in the processingsection 21 of the terminal apparatus 2. The display section 24 may be adisplay device provided in the main body unit of the terminal apparatus2, or may be a display device separated from the main body unit. Theterminal apparatus 2 may include a speaker, a microphone, and/or acamera, etc.

The terminal apparatus 2 includes a communication section 25. In thepresent embodiment, the communication section 25 has a function ofperforming communication while being connected to a mobile communicationnetwork (in other words, a mobile telephone communication network). Thatis, the terminal apparatus 2 (specifically, the processing section 21)is connected to the network 3 by using the communication section 25 (inother words, through the communication section 25) via the mobilecommunication network, and communicates with other devices (e.g., theserver 1, etc.). Using the communication section 25, the processingsection 21 transmits information to the other devices and receivesinformation from the other devices. The configuration of thecommunication section, through which the terminal apparatus 2 performscommunication via the network 3, is arbitrary. For example, thecommunication section 25 may have a function of connecting to a wirelessLAN through a communication module with Wi-Fi authentication, or mayhave both the function of connecting to the mobile communication networkand the function of connecting to the wireless LAN.

[2. Outline of Process in Information Processing System]

Processes to be executed in an information processing system accordingto the present embodiment will now be outlined. In the presentembodiment, the information processing system executes a summon game ina game application. In the summon game, the user is granted a gamecharacter corresponding to a selection candidate that is selected by theuser from among a predetermined initial number (here, five) of selectioncandidates that have been chosen by a draw (a computer-simulated draw).Note that in the game of the present embodiment, granting of a gamecharacter to the user in a summon game is represented as a gamecharacter being summoned from another world. Therefore, in the presentembodiment, granting a game character to the user is referred to as“summoning”, and the game in which a game character is granted to theuser is referred to as a summon game.

In the present embodiment, in addition to the summon game, a game thatis played by using a game character that has been granted to the user inthe summon game is also played in the game application. Note that a gamecharacter is not limited to a human-shaped game object (e.g., a playercharacter controlled by the user), but also includes game objects suchas weapons and items used in the game. The game that is played by usinga game character may be of any content, and it may be a game such as asimulation game, a puzzle game, an action game or a race game.

[2-1. Flow of Summon Game Mode]

FIG. 4 shows an example of a flow of a summon game mode in the presentembodiment. In the present embodiment, the summon game mode in which thesummon game is played includes the normal summon mode (step S2, S3) andthe designated summon mode (step S6, S7).

The normal summon mode is a mode in which the user is granted a gamecharacter corresponding to the selection candidate selected by the userfrom among the selection candidates that have been chosen by a draw.Note that as will be later described in detail, when selecting fromselection candidates in the normal summon mode, the selection candidatescorresponding to game characters are displayed in such a manner that thegame characters cannot be uniquely identified. The designated summonmode is a mode in which the user is granted a game character that isdesignated by the user from among particular game characters that arepredetermined in the game application. In the designated summon mode,the particular game characters are displayed in such a manner that thegame characters can be uniquely identified. Thus, in the normal summonmode, it is uncertain which game character the user can obtain, whereasin the designated summon mode, it is ensured that the user can obtain adesired game character from among the particular game characters.

[2-1-1. At Start of Normal Summon Mode]

As shown in FIG. 4, when the summon game is executed for the first time,the normal summon mode is executed (i.e., the summon game is executed inthe normal summon mode). In this case, the terminal apparatus 2 displaysa normal start image on the display section 24 (step S1). The normalstart image is a user interface image used for receiving, from the user,a start instruction for starting the normal summon mode. The details ofthe normal start image will now be described with reference to FIG. 5.

FIG. 5 is a diagram showing an example of the normal start image. Asshown in FIG. 5, the normal start image includes a content image 31 thatrepresents the content of the summon game. Here, in the presentembodiment, it is assumed that the game application has different summongames. For example, a different game character may be more likely to bechosen by a draw in each summon game, or each summon game may use adifferent set of game characters from which game characters are chosenby a draw. There may be a certain game character that can be selectedonly in a particular summon game. Note that in the present embodiment, aparticular summon game (a summon game called “SUMMON NEW CHARACTER” tobe described below) can be executed both in the normal summon mode andin the designated summon mode. On the other hand, other summon games maybe executable only in the normal summon mode while being not executablein the designated summon mode.

As the content of a summon game, the content image 31 includes the nameof the summon game (“SUMMON NEW CHARACTER” in FIG. 5). In the presentembodiment, the content image 31 shows, as the content of the summongame, some of the game characters that can be selected in the summongame (here, rare characters to be described below) (see FIG. 5). As willbe later described in detail, in the present embodiment, each gamecharacter is assigned an attribute. The content image 31 includes imagesrepresenting the game characters as well as images of attribute symbolsrepresenting attributes assigned to the game characters (see FIG. 5).

As shown in FIG. 5, the normal start image includes a period image 32that represents the period in which the summon game represented by thecontent image 31 is executable. In the present embodiment, theexecutable period is set for each summon game. The period in which thesummon game is executable is a period that is defined in real time,e.g., from Mar 1, 2020 to Mar 31, 2020. In the present embodiment, theperiod image 32 includes information that represents the remainingamount of time for which the summon game is executable, such as “20 DAYSLEFT”, for example.

As shown in FIG. 5, the normal start image includes a plurality ofsummon game icons 33. Each summon game icon 33 represents one of aplurality of summon games provided in the game application that isexecutable at present. In the example shown in FIG. 5, six summon gamesare executable, and six summon game icons 33 are displayed. The drawicon that represents the summon game currently selected (i.e., thesummon game corresponding to the content image 31) is displayed in amanner different from that for the other draw icons, which are notcurrently selected. Note that in FIG. 5, hatching is used to representthe difference in the manner of display of the draw icon.

As shown in FIG. 5, the normal start image includes switch instructionimages 34 and 35 used for giving a switch instruction to switch theselected summon game to another. That is, in response to the userperforming an input on the switch instruction image 34 or 35, theselected summon game is switched to another, and the content image 31and the period image 32 are also switched accordingly. Note thatalthough it is assumed in the present embodiment, that an inputperformed on various images displayed on the display section 24 of theterminal apparatus 2 is performed by touching on the images, forexample, the method by which the user performs an input for giving aninstruction may be any method.

As shown in FIG. 5, the normal start image includes a start button image36 used for giving a start instruction to start the normal summon mode.That is, in response to a start instruction having been given by theuser by performing an input on the start button image 36, the summongame being selected is started in the normal summon mode. Thus, byperforming an input on the switch instruction images 34 and 35, the usercan select a desired summon game from among a plurality of summon gamesexecutable, and by performing an input on the start button image 36while the desired summon game is selected, the user can start the summongame.

Here, in the present embodiment, summoning in the summon game (i.e.,granting of a game character to the user) is performed in exchange forconsumption of summon points that are used in the game (note howeverthat summoning can be performed without consuming summon points undercertain conditions in the present embodiment). Therefore, the startbutton image 36 includes information that represents the amount ofsummon points to be consumed in exchange for summoning in response to aninput performed on the start button image 36. In the example shown inFIG. 5, it is indicated that five summon points will be consumed forsummoning in response to an input performed on the start button image36. Note that the summon points may represent the number of particularitems owned by the user in the game, for example.

As shown in FIG. 5, the normal start image includes a point ownershipimage 37 that indicates the amount of summon points currently owned bythe user. In the present embodiment, the user can obtain summon pointsby purchasing summon points with real currency or by satisfyingconditions in the game application (e.g., clearing a particular gamestage).

As shown in FIG. 5, the normal start image includes a ticket ownershipimage 38 that represents the number of tickets currently owned by theuser. A ticket is an item in the game and is an example of an item withwhich it is possible to summon without consuming summon points. In thepresent embodiment, it is possible to start a summon in the summon gamein exchange for consuming one ticket instead of consuming summon points.In the present embodiment, the user can obtain a ticket by satisfying acondition in the game application.

Note that when a summon is performed while the user owns both summonpoints and a ticket, either summon points or a ticket may be consumedpreferentially over the other, or the user may be allowed to specifywhich one to consume. Note that the method for summoning withoutconsuming summon points is not limited to the method of summoning byconsuming a ticket. For example, in other embodiments, the informationprocessing system may allow the first summon in the summon game to beperformed without consuming summon points.

As shown in FIG. 5, the normal start image includes a cumulative grantcount image 39 that represents the cumulative grant count. Thecumulative grant count refers to the cumulative number of times a gamecharacter has been granted to the user by summoning in the summon game(here, a summon game named “SUMMON NEW CHARACTER”). As will be laterdescribed in detail, in the present embodiment, execution of thedesignated summon mode described above is permitted on the conditionthat the cumulative grant count has become equal to a predeterminedpermit count (here, 40 times). In the present embodiment, the cumulativegrant count image 39 shows the current cumulative grant count (27 in theexample shown in FIG. 5) and the permit count.

As described above, in the present embodiment, the informationprocessing system displays information that represents the cumulativegrant count on the display device while the information processingsystem is ready to accept a start instruction of the normal summon mode(i.e., in a state in which the normal start image is displayed). Then,the user can decide whether or not to execute the normal summon mode sothat execution of the designated summon mode is permitted, by referringto the cumulative grant count, thereby improving the convenience of theuser.

Note that although not shown, the normal start image may include abutton image used for giving an instruction to display a menu image or abutton image used for giving an instruction to start another game otherthan the summon game. When an input is performed on these button images,the terminal apparatus 2 ends the summon game mode.

[2-1-2. Selection of Selection Candidates]

When the start instruction is given while the normal start image isdisplayed, the normal summon mode is started. At this time, first, theterminal apparatus 2 displays a candidate selection image on the displaysection 24 (step S2 shown in FIG. 4). The candidate selection image is auser interface image used for accepting a selection instruction from theuser to select one of the selection candidates. The details of thecandidate selection image will now be described with reference to FIG.6.

FIG. 6 shows an example of a candidate selection image. As shown in FIG.6, the candidate selection image includes five attribute symbols 41 to45, which are five selection candidates from which the user can make aselection. The attribute symbols 41 to 45 represent the attributes ofthe game characters that have been chosen by a draw, which are gamecharacters corresponding to the selection candidates

Here, in the present embodiment, each game character has one of thefollowing attributes: red attribute, blue attribute, green attribute andcolorless attribute. Note that for each game character, the server 1stores information representing the attribute assigned to the gamecharacter in association with the game character. In the presentembodiment, the attribute symbols representing the attributes aredisplayed in colors of the respective attributes. Note that in FIG. 6,the different colors of the attribute symbols are represented bydifferent hatching (this similarly applies to other figures).

Note that the attribute of a game character is information that isassigned to each game character and is an example of a property that isassigned to the game character. The property of a game character meansto include, for example, type, state, ability, etc., of the gamecharacter, as well as the attribute of the game character. The propertyof a game character can be any information based on which the gamecharacter can be classified into a number of classes (fewer than thenumber game characters). Note that in other embodiments, multipleproperties (specifically, attributes) may be assigned to one gamecharacter. Then, an attribute symbol may represent any one of aplurality of attributes assigned to the game character. An attribute ofa game character (which is assigned a plurality of attributes) that isrepresented by the attribute symbol may be randomly determined, may bepredetermined, or may be determined according to a predeterminedcondition (e.g., a condition related to parameters of the gamecharacter).

Note that the number of selection candidates presented when the normalsummon mode is started (i.e., the initial candidate count) is five inthe present embodiment, but the initial candidate count in otherembodiments does not need to be fixed and may be variable. For example,the initial candidate count may vary for different summon games, or theinitial candidate count may change randomly.

In the present embodiment, when the start instruction is given, theinformation processing system chooses, by a draw, five game charactersthat are to be selection candidates from among game characters that areobjects of the draw (i.e., game characters that can be granted to theuser). Then, attribute symbols that represent the attributes of thechosen game characters are displayed on the terminal apparatus 2 asselection candidates. Thus, in the present embodiment, in the normalsummon mode, the user cannot uniquely identify game characters, whichare selection candidates, but can select one of the selection candidatesin a state in which the user can recognize the attribute of the gamecharacter.

Note that the specific method of the draw to choose game characters tobe selection candidates may be any method. For example, the server 1stores information in which each game character, which is an object ofthe draw, is associated with a numerical value that represents theselection probability. The server 1 performs the draw using a randomnumber so that each game character will be chosen with the probabilitybased on the numerical value. Note that this numerical value may be anumerical value expressed in percentage or a numerical value thatrepresents the degree of selection probability (e.g., the higher thenumerical value, the more likely the game character will be chosen).

In the present embodiment, the game characters are classified into aplurality of groups with different selection probabilities.Specifically, game characters are classified into two groups: normalcharacters and rare characters for which the selection probability isset to be lower than normal characters. Note that the game charactersclassified as normal characters do not need to have a constant selectionprobability, and the game characters classified as rare characters donot need to have a constant selection probability. For example, normalcharacters may be further classified into the first group of a higherselection probability and a second group of a lower selectionprobability (but higher than the selection probability of rarecharacters). The selection probabilities of the normal characters and/orthe rare characters may vary between different summon games.

As shown in FIG. 6, the candidate selection image includes a selectionwindow 46. The selection window 46 includes a message that prompts theuser to select an attribute symbol (the message “SELECT ONE” in FIG. 6).The selection window 46 also includes a selection confirm button 47 usedfor giving a selection instruction to select a selection candidate.While the candidate selection image is displayed, the user firstperforms an input of specifying one of the attribute symbols 41 to 45,and further performs an input on the selection confirm button 47,thereby giving a selection instruction. This means that the designatedattribute symbol (i.e., a selection candidate) has been selected.

When the user gives a selection instruction, the game charactercorresponding to the selected attribute symbol is granted to the user(step S3 shown in FIG. 4). Specifically, the terminal apparatus 2displays on the display section 24 a special effects image that showsthe game character being summoned to appear, and grants the gamecharacter to the user.

In the present embodiment, in a single iteration of the normal summonmode started by the start instruction, the user can select at least oneand a maximum of five attribute symbols from among the five attributesymbols chosen by a draw. That is, when a selection instruction is givenwhile the candidate selection image shown in FIG. 6 is displayed, theuser may either further give a selection instruction by continuing thenormal summon mode or end the normal summon mode without giving afurther selection instruction (see FIG. 4).

FIG. 7 shows another example of a candidate selection image. Thecandidate selection image shown in FIG. 7 is one that is displayed onthe display section 24 after one game character has been granted inresponse to a selection instruction given for the candidate selectionimage shown in FIG. 6. Note that it is assumed herein that a selectioninstruction has been given to select the attribute symbol 44 among theattribute symbols 41 to 45 included in the candidate selection imageshown in FIG. 6.

As shown in FIG. 7, in the candidate selection image displayed after theattribute symbol 44 is selected, a character image 51 that represents agame character corresponding to the attribute symbol 44 is displayedinstead of the attribute symbol 44. Therefore, in the state shown inFIG. 7, the number of selection candidates is four.

Note that in the present embodiment, the character image 51 includes animage (an image of three stars in FIG. 7) that represents the raritylevel in accordance with the selection probability of the gamecharacter. In the present embodiment, the rarity level is represented bythree or four stars for normal characters described above, and therarity level is represented by five stars for rare characters describedabove. Thus, by looking at the candidate selection image, the user cansee game characters that have been granted in the current iteration ofthe normal summon mode and the rarity levels thereof.

As shown in FIG. 7, the candidate selection image that is displayedafter a game character has been granted includes a continuation confirmwindow 52. The continuation confirm window 52 includes a message askingthe user whether or not to continue the normal summon mode (the message“DO YOU WANT TO CONTINUE SUMMONING BY CONSUMING FOUR SUMMON POINTS?” inFIG. 7). The continuation confirm window 52 includes a back button image53 and a continue button image 54. The back button image 53 is a buttonimage used for giving an end instruction to end the normal summon modebeing currently executed. That is, in response to an input performed bythe user on the back button image 53, the terminal apparatus 2 ends thenormal summon mode and displays a start image (specifically, the normalstart image described above or the designated start image to bedescribed below) on the display section 24.

The continue button image 54 is a button image used for giving acontinue instruction to continue the normal summon mode being executed.That is, in response to an input performed by the user on the continuebutton image 54, the terminal apparatus 2 erases the continuationconfirm window 52 and displays the selection window 46 in place of thecontinuation confirm window 52 (see FIG. 6). This allows the user togive a selection instruction again.

Thus, in the present embodiment, each time a game character is grantedto the user in response to a selection instruction, the continuationconfirm window 52 is displayed, and the user can select whether to endor to continue the normal summon mode. Then, if the user keeps selectingin the normal summon mode, the user can give the selection instructionfive times. Note that after the fifth selection instruction is given,the terminal apparatus 2 ends the normal summon mode and displays thestart image again (see FIG. 4). Note that when ending the normal summonmode, the terminal apparatus 2 may display the start image afterdisplaying an image representing the five game characters granted (e.g.,an image including images of the game characters instead of theattribute symbols in the candidate selection image) as an imagerepresenting the result of the current iteration of the normal summonmode.

Note that in the present embodiment, since summon points are consumedfor each summon, the second and subsequent selections in a singleiteration of the normal summon mode are also done in exchange forconsuming summon points. That is, in the present embodiment, the usermay give a start instruction or a continue instruction described abovein exchange for consuming summon points. Here, in the presentembodiment, the amount of summon points to be consumed for a startinstruction or a continue instruction in a single iteration of thenormal summon mode is determined based on the number of summonsperformed in a single iteration of the normal summon mode. Specifically,a start instruction to perform the first summon in the normal summonmode can be given in exchange for consuming five summon points. Acontinue instruction to perform the second to fourth summon in thenormal summon mode can be given in exchange for consuming four summonpoints per instruction. A continue instruction to perform the fifthsummon in the normal summon mode can be given in exchange for consumingthree summon points. Thus, in the present embodiment, it can be saidthat the amount of summon points to be consumed for a start instructionor a continue instruction is determined based on the number of selectioncandidates that have been unselected in the current iteration of thenormal summon mode.

In the present embodiment, the continue button image 54 includesinformation that represents the amount of summon points (here, four) tobe consumed for a selection instruction using the continue button image54. The continuation confirm window 52 includes a change-of-points image55 that represents the change of summon points owned by the user whenthe selection instruction is given. With the continue button image 54,the user can check the summon points to be consumed for a selectioninstruction, and with the change-of-points image 55, the user can checkthe number of points owned by the user before and after the selectioninstruction.

Thus, in the present embodiment, if the user performs five iterations ofthe normal summon mode while selecting only one selection candidate ineach iteration, a total of 25 summon points will be consumed. Incontrast, if the user selects all of the five selection candidates in asingle iteration of the normal summon mode, a total of 20 summon pointswill be consumed. That is, in the latter case, as compared with theformer case, it is possible to reduce the amount of summon points to beconsumed for selecting five selection candidates. In the presentembodiment, the candidate selection image includes an informationnotification window 48 (see FIG. 6 and FIG. 7), and the informationnotification window 48 includes a message indicating that theconsumption of summon points can be reduced by successively givingselection instructions in a single iteration of the normal summon mode(the message “YOU CAN SUMMON USING FEWER POINTS IF YOU SUMMONSUCCESSIVELY” in FIG. 6 and FIG. 7).

On the other hand, in the present embodiment, since attribute symbolsare displayed in the candidate selection image, the user can guess,based on the attribute symbols, whether there is a possibility ofobtaining a desired game character in the current iteration of thenormal summon mode. For example, where a game character desired by theuser is of the red attribute, assume a case where two of the fiveattribute symbols displayed in the candidate selection image are of thered attribute. In this state, the user will not obtain the desired gamecharacter by selecting any of the three non-red attribute symbols, andin order to obtain the desired game character, the user can employ astrategy of selecting the two red attribute symbols, ending the normalsummon mode, and then starting a new iteration of the normal summonmode. In the state described above, the user may also employ a strategyof selecting the five attribute symbols in order to reduce the number ofsummon points to be consumed.

Thus, in the present embodiment, the user may draw using any of twostrategies in the normal summon mode: (a) reducing the consumption ofsummon points by continuing the normal summon mode, and (b) ending aniteration of the normal summon mode in the middle and then starting anew iteration of the normal summon mode in order to increase theprobability of obtaining the desired game character. Therefore, it ispossible to enhance the strategic aspect of the summon game and improvethe playability of the game.

As shown in FIG. 6 and FIG. 7, the candidate selection image includesthe cumulative grant count image 39. That is, the information processingsystem updates (e.g., increments) the cumulative grant count in thenormal summon mode, and displays the updated cumulative grant countimage 39 representing the cumulative grant count on the display section24. Note that as described above, in the present embodiment, executionof the designated summon mode is permitted when the cumulative grantcount becomes equal to the permit count. Therefore, the informationnotification window 48 included in the candidate selection imageincludes a message indicating that execution of the designated summonmode will be permitted when a number of summons equal to the permitcount are performed (the message “DESIGNATED SUMMON MODE IS UNLOCKEDWHEN YOU SUMMON 40 TIMES!” in FIG. 6 and FIG. 7).

As described above, in the present embodiment, the informationprocessing system displays on the display device informationrepresenting the cumulative grant count, together with the selectioncandidates, during the normal summon mode. Then, since the user cancheck the cumulative grant count while in the normal summon mode, theuser can determine whether or not to continue the normal summon mode byreferring to the cumulative grant count. This improves the convenienceof the user.

Note that in the present embodiment, the information processing systemconsumes summon points and updates the cumulative grant count at a pointin time when the start instruction or the continue instruction isconfirmed. For example, in the candidate selection image shown in FIG.6, a start instruction has been given in the normal start image shown inFIG. 5 but a selection instruction has not been given. Therefore, a gamecharacter has therefore not been granted but the cumulative grant counthas been updated (in the state shown in FIG. 6, the cumulative grantcount has been incremented by one from the state shown in FIG. 5). Thisis because in the present embodiment, confirmation of the startinstruction or the continue instruction by the user in turn confirms theconsumption of summon points and the granting of the game character tothe user.

Note that there is no limitation on when the information processingsystem updates the cumulative grant count, and the informationprocessing system may update the cumulative grant count at a differentpoint in time in other embodiments. For example, the informationprocessing system may update the cumulative grant count at a point intime when a selection instruction is given or may update the cumulativegrant count at a point in time when a game character is granted to theuser.

In the present embodiment, when receiving various instructions by theuser (e.g., a selection instruction, a start instruction, etc.), theterminal apparatus 2 may display an instruction confirm window. Forexample, when a start instruction is received by the user, the terminalapparatus 2 may display the message “START?” and an instruction confirmwindow that includes a back button image and an execute button image.Then, when an input is performed on the execute button image, theterminal apparatus 2 may determine that the start instruction has beenconfirmed. On the other hand, when an input is performed on the backbutton image, the terminal apparatus 2 may determine that the selectioninstruction has not been confirmed, erase the instruction confirmwindow, and go back to the state in which the terminal apparatus 2 isready to accept a start instruction.

Note that in the present embodiment, the information processing systemalso counts, as the cumulative grant count, the number of times a gamecharacter is granted through a summon that is performed withoutconsuming summon points (e.g., a summon that is performed in exchangefor consuming a ticket described above), as well as the number of timesa game character is granted through a summon that is performed inexchange for consuming summon points. That is, under certain conditions(e.g., on the condition that a tickets is consumed), the informationprocessing system accepts a selection instruction not in exchange fordecreasing summon points and grants a game character corresponding tothe selection candidate selected by the selection instruction to theuser. Then, the information processing system calculates the cumulativegrant count as the sum between the number of times a game character isgranted by a selection instruction that is accepted in exchange forconsuming summon points and the number of times a game character isgranted by a selection instruction that is accepted not in exchange fordecreasing summon points. Then, the user can increase the cumulativegrant count by a plurality of methods. That is, the user is allowed tochoose the method for increasing the cumulative grant count, thusimproving the strategic aspect of the game. According to the descriptionabove, the number of times a game character has been actually grantedand the cumulative grant count can be matched with each other so thatthe cumulative grant count is a value that is easy to understand for theuser. Note that in other embodiments, the information processing systemmay update the cumulative grant count only when a game character isgranted by a selection instruction that is accepted in exchange forconsuming summon points, while not updating the cumulative grant countwhen a game character is granted by a selection instruction that isaccepted not in exchange for decreasing summon points.

In the present embodiment, the information processing system counts, asthe cumulative grant count, the number of times a game character isgranted in one summon game (specifically, the summon game named “SUMMONNEW CHARACTER”), while not counting, as the cumulative grant count, thenumber of times a game character is granted in other summon games. Thatis, the information processing system accepts start instructions forstarting different normal summon modes, between which the drawprobability is varied for at least one game character, updates thecumulative grant count for at least one of the normal summon modes, andupdates the cumulative grant count for each normal summon mode. Then,the user can play summon games while giving a consideration as towhether the user should play a particular summon game in an attempt toexecute the designated summon mode or should play other summon games inan attempt to obtain a desired game character, thus improving thestrategic aspect of the summon game.

[2-1-3. Process Performed when Cumulative Grant Count Becomes Equal toPermit Count]

When the cumulative grant count becomes equal to the permit count whilein the normal summon mode, the information processing system permitsexecution of the designated summon mode. In this case, the terminalapparatus 2 displays, on the display section 24, a permit notificationwindow for notifying the user that execution of the designated summonmode has been permitted (step S4 shown in FIG. 4).

FIG. 8 is a diagram showing an example a permit notification window. Asshown in FIG. 8, a permit notification window 61 includes a messageindicating that execution of the designated summon mode has beenpermitted (the message “SUMMON COUNT REACHED 40. DESIGNATED SUMMON MODEIS NOW UNLOCKED.” in FIG. 8). Note that in the present embodiment, thepermit notification window 61 is displayed superimposed over thecandidate selection image after displaying a special effects image thatshows the game character selected by the selection instruction by theuser being grated to the user.

As described above, in the present embodiment, when the cumulative grantcount becomes equal to or greater than a reference count (e.g., thepermit count) during an iteration of the normal summon mode, theinformation processing system notifies the user, while in the iterationof the normal summon mode, that execution of the designated summon modehas been permitted. Thus, the user can learn in the normal summon modethat execution of the designated summon mode has been permitted, and theuser can determine whether to continue the normal summon mode or to endthe normal summon mode at a point in time when execution of thedesignated summon mode is permitted.

As shown in FIG. 8, the permit notification window 61 includes a buttonimage 62 used for giving an instruction to close the permit notificationwindow 61. In response to an input performed by the user on the buttonimage 62, the permit notification window 61 is erased.

When the permit notification window 61 is erased, the candidateselection image is displayed on the display section 24. Thus, theterminal apparatus 2 is ready to accept a continue instruction or an endinstruction as described above on the continuation confirm window 52.Note that although the continuation confirm window 52 is displayed,together with the permit notification window 61, in the example shown inFIG. 8, the terminal apparatus 2 does not accept an input performed onthe button images 53 and 54 of the continuation confirm window 52 whilethe permit notification window 61 is displayed. After the cumulativegrant count becomes equal to the permit count, the informationnotification window 48 no longer displays a message indicating thatexecution of the designated summon mode is permitted by performing anumber of summons equal to the permit count (i.e., the message“DESIGNATED SUMMON MODE IS UNLOCKED WHEN YOU SUMMON 40 TIMES!”) becausethere is little need to notify the user.

As described above, even after the permit notification window 61 isdisplayed, just as before the permit notification window 61 isdisplayed, the user can choose to continue or end the normal summon mode(FIG. 4). Note however that when the five selection candidates of thecurrent iteration of the normal summon mode have all been selected whenthe permit notification window 61 is displayed, the permit notificationwindow 61 is erased and the normal summon mode is ended. In this case,after ending the normal summon mode, the designated start image to bedescribed below is displayed on the display section 24 (step S5 shown inFIG. 4).

[2-1-4. Designated Summon Mode]

When the normal summon mode is ended after execution of the designatedsummon mode is permitted in the normal summon mode, the next summon gameis executed in the designated summon mode (steps S6 and S7 shown in FIG.4). In the designated summon mode, from among a plurality of (here,four) particular game characters determined in the game application, agame character that is designated by the user is granted to the user. Inthe normal summon mode, the user obtains a game character by selectingone selection candidate from a set of selection candidates that havebeen chosen by a draw while the selection candidates are displayed insuch a manner that game characters cannot be uniquely identified (i.e.,while attribute symbols thereof are displayed). In contrast, in thedesignated summon mode, the user obtains a game character by specifyingone game character from a set of particular game characters while thegame characters are displayed in such a manner that the game characterscan be uniquely identified.

Note that in the present embodiment, one or more game charactersdisplayed in the designated summon mode is/are rare character/charactersdescribed above. That is, in the normal summon mode, the informationprocessing system displays on the display device a set of selectioncandidates corresponding to game characters that are chosen by aprobability-based draw from among a plurality of game charactersincluding normal characters and rare characters, and in the designatedsummon mode, the information processing system displays on the displaydevice a rare character or rare characters as one or more gamecharacters displayed in the designated summon mode. That is, in thepresent embodiment, in the designated summon mode, it is ensured thatthe user can obtain rare characters, which are more difficult to obtainin the normal summon mode. Thus, it is possible to more stronglymotivate the user to perform the designated summon mode (hence toperform the normal summon mode so that execution of the designatedsummon mode is permitted).

Note that rare characters that can be granted in the normal summon modedo not all need to be presented in the designated summon mode. In thepresent embodiment, there are five or more rare characters that can begranted in the normal summon mode, whereas four of them are presented inthe designated summon mode.

If the normal summon mode is ended after execution of the designatedsummon mode is permitted, the terminal apparatus 2 displays thedesignated start image on the display section 24 (step S5 shown in FIG.4). The designated start image is a user interface image used foraccepting a start instruction for starting the designated summon modefrom the user. The details of the designated start image will now bedescribed with reference to FIG. 9.

FIG. 9 is a diagram showing an example of the designated start image. Asshown in FIG. 9, the designated start image includes images 31 to 39similar to the normal start image (see FIG. 5). Note however that themanner in which the start button image 36 and the cumulative grant countimage 39 are displayed in the designated start image is different fromthat in the normal start image. Specifically, in the designated startimage, the start button image 36 and the cumulative grant count image 39are outlined differently from the normal start image. Thus, the user canrecognize that a mode that is different from the normal summon mode(i.e., the designated summon mode) is being executed. The start buttonimage 36 includes a message indicating the designated summon mode (themessage “DESIGNATED SUMMON” in FIG. 9). Note that a rare character canbe summoned without consuming summon points in the designated summonmode, and this may be indicated by the start button image 36. Therefore,the user can recognize the details of summoning in the designated summonmode.

As described above, in the present embodiment, when the cumulative grantcount becomes equal to or greater than a reference count (i.e., thepermit count) during an iteration of the normal summon mode, theinformation processing system notifies that execution of the designatedsummon mode has been permitted while the information processing systemis ready to accept a start instruction in the designated summon modeafter the end of the iteration of the normal summon mode. Then, it ispossible to reduce the probability of the user forgetting to perform thedesignated summon mode.

In the present embodiment, the content image 31 included in each startimage shows four rare characters, which are the particular gamecharacters described above. Therefore, the user knows rare charactersthat the user can obtain in the designated summon mode not only after,but also before, the permission of execution of the designated summonmode.

Note that the game characters displayed in the designated summon mode inthe present embodiment are particular game characters that arepredetermined in the game application, but they do not need to bepredetermined. For example, in other embodiments, game characters thathave been chosen by a draw from among the rare characters may bedisplayed in the designated summon mode.

When starting the designated summon mode, the user gives a startinstruction by performing an input on the start button image 36. Notethat also in the designated summon mode as in the normal summon mode,the user may end the summon game mode by performing an input on a buttonimage used for giving an instruction to display the menu image or on abutton image used for giving an instruction to start another game otherthan summon games.

When a start instruction is given while in a state in which thedesignated start image is displayed, the designated summon mode isstarted. Then, first, the terminal apparatus 2 displays a characterdesignation image on the display section 24 (step S6 shown in FIG. 4).The character designation image is a user interface image used foraccepting, from the user, a designation instruction for designating oneof the particular game characters. The details of the characterdesignation image will now be described with reference to FIG. 10.

FIG. 10 is a diagram showing an example of a character designationimage. As shown in FIG. 10, the character designation image includescharacter images 71 to 74 representing four game characters that can bedesignated by the user. Thus, in the character designation image, theuser can designate a game character while game characters are displayedin such a manner that they can be uniquely identified by the user. Notethat in the present embodiment, a character images 71 to 74 includeattribute symbol images representing the attributes of the gamecharacters. Therefore, the user can recognize the attribute of each gamecharacter when designating the game character.

As shown in FIG. 10, the character designation image includes aninstruction window 75. The instruction window 75 includes a message thatprompts the user to designate a game character (the message “SELECT ONE”in FIG. 10). The instruction window 75 includes a designation confirmbutton 76 for giving a designation instruction to designate a gamecharacter. While in a state in which the character designation image isdisplayed, the user gives a designation instruction by first performingan input of designating one of a character images 71 to 74 and furtherperforming an input on the designation confirm button 76. This confirmsthat a game character has been designated.

As a designation instruction is given by the user, the designated gamecharacter is granted to the user (step S7 shown in FIG. 4).Specifically, the terminal apparatus 2 displays on the display section24 a special effects image that shows the game character being summonedto appear, and grants the game character to the user.

In the present embodiment, the number of game characters that can bedesignated by the user in the designated summon mode is one. Therefore,when the game character designated by the designation instruction isgranted to the user while in a state in which the character designationimage is displayed, the designated summon mode is ended and the normalsummon mode is executed (see FIG. 4). Note that the characterdesignation image includes an information notification window 77, whichincludes a message indicating that the number of game characters thatcan be designated by the user is one (the message “THIS MODE ENDS AFTERONE SUMMON.” in FIG. 10). Therefore, the user can recognize the numberof game characters that can be designated in the designated summon mode.

Note that there is no limitation on the number of game characters thatcan be designated by the user in the designated summon mode. Forexample, in other embodiments, the user may be allowed to designate apredetermined number (two or more) of game characters from among aplurality of game characters presented in the character designationimage.

As described above, in the present embodiment, in the summon game mode,the information processing system executes the designated summon mode,in addition to the normal summon mode in which a game character isgranted to the user by a draw. Therefore, even if the user cannot obtaina particular game character in the normal summon mode, it is possiblefor the user to obtain the particular game character by performing anumber of summons equal to the permit count. Thus, since the userperforms the normal summon mode while thinking whether or not to keepsummoning until the cumulative grant count becomes equal to the permitcount, it is possible to improve the strategic aspect of the summongame. In the present embodiment, as the designated summon mode is mademore advantageous for the user than the normal summon mode (e.g., it iseasier to obtain a rare character), it is possible to motivate the userto perform more summons in the normal summon mode, and to promote theconsumption of summon points by the user.

In the present embodiment, when the cumulative grant count becomes equalto or greater than the permit count, the information processing systemallows the designated summon mode to be started while prohibitingstarting a new iteration of the normal summon mode. More specifically,the information processing system prohibits starting the normal summonmode until completion of the process of granting a game character to theuser in the designated summon mode. Therefore, it is possible to promptthe user to immediately perform the designated summon mode withoutstarting a new iteration of the normal summon mode. In the presentembodiment, if execution of the designated summon mode is permittedduring an iteration of the normal summon mode, the user may possiblyforget to play the summon game in the designated summon mode aftercompletion of the iteration of the normal summon mode. In contrast, withthe configuration described above, when the user next attempts to playthe summon game, the designated summon mode is executed, therebylowering the possibility.

Note that the present embodiment sets a period in which the summon gamecan be executed. That is, the information processing system accepts astart instruction to start the normal summon mode and a startinstruction to start the designated summon mode within a predeterminedperiod in real time. When a period in which the summon game can beexecuted is set as described above, it is possible to lower thepossibility of the user forgetting to play the summon game in thedesignated summon mode, so that the user is more likely to play thesummon game in the designated summon mode in the period.

In the present embodiment, even after the cumulative grant count becomesequal to or greater than the permit count while in the normal summonmode, the information processing system accepts a selection instructionuntil the end process of ending the normal summon mode is performed (seeFIG. 4). Then, in the state described above, it is possible to allow theuser to choose whether to give a selection instruction by continuing thenormal summon mode or to end the normal summon mode, thus improving thestrategic aspect of the summon game.

Note that in the present embodiment, in the normal summon mode, theinformation processing system displays selection candidates on thedisplay device in such a manner that a part of the property (e.g., theattribute) is shown for the game characters corresponding to theselection candidates. Therefore, based on the property shown for eachselection candidate, the user can guess the game character correspondingto the selection candidate and can determine whether any of theselection candidates may correspond to the game character desired by theuser, thus improving the strategic aspect of the summon game in thenormal summon mode. In the present embodiment, it is possible to allowthe user to choose whether to continue or end the normal summon modeunder such circumstances that the user can make such guess anddetermination, thereby further improving the strategic aspect of thesummon game. For example, when the cumulative grant count becomes equalto or greater than the permit count while in the normal summon mode, ifthere remains a selection candidate that indicates the attribute of thegame character desired by the user, the user plays the summon game whilethinking whether to continue or end the normal summon mode, thusimproving the playability of the summon game.

In the present embodiment, in the normal summon mode, when there is onlya few selection candidates that are unselected, the amount of summonpoints to be consumed is smaller as compared with a case where there aremore selection candidates that remain unselected. That is, when theinformation processing system receives a selection instruction in astate in which the number of unselected selection candidates is equal tothe first number (e.g., one), the amount by which a predeterminedparameter is decreased (e.g., the amount by which summon points aredecreased) for a selection instruction is smaller than that in a statein which the number of unselected selection candidates is equal to thesecond number (e.g., five) greater than the first number. Therefore, inthe present embodiment, when the cumulative grant count becomes equal toor greater than the permit count during an iteration of the normalsummon mode, the user can give a consideration as to whether to continuethe normal summon mode in order to efficiently make a selection withfewer point consumption or to end the normal summon mode in order tosooner execute the designated summon mode. According to the presentembodiment, while the user gives such a consideration, it is possible toallow the user to choose whether to continue or end the normal summonmode, thus improving the strategic aspect of the summon game.

In the present embodiment, game characters that can be granted in thedesignated summon mode are game characters that can be chosen to beselection candidates by a draw in the normal summon mode. Therefore,according to the present embodiment, even if the user fails to obtain adesired game character in the normal summon mode, it is ensured that theuser can obtain the desired game character in the designated summonmode. Therefore, it is possible to more strongly motivate the user torepeatedly perform the normal summon mode.

In the present embodiment, when a game character is granted in thedesignated summon mode, the user's summon points are not consumed. Thatis, the information processing system grants to the user the gamecharacter designated by the user not in exchange for decreasing summonpoints. Thus, it is possible to more strongly motivate the user tosummon in the normal summon mode until the cumulative grant countbecomes equal to the permit count so as to achieve a state in whichexecution of the designated summon mode is permitted. Note that in otherembodiments, a game character may be granted in the designated summonmode in exchange for consuming a predetermined amount of summon points.

In the present embodiment, the information processing system permitsexecution of the designated mode until the number of times thedesignated summon mode is executed becomes equal to a predeterminedupper limit number of times (here, one time). That is, during a periodin which the summon game can be executed, the user can execute thedesignated summon mode for the predetermined number of times. If thenumber of times the designated summon mode can be executed wereunlimited, the user would be able to obtain an unlimited number ofparticular game characters (e.g., rare characters) in the designatedsummon mode. This may possibly lower the value of such game characters,and lower the motivation for performing the normal summon mode, which isthe summon game for obtaining such game characters. In contrast, in thepresent embodiment, there is an upper limit to the number of times thedesignated summon mode can be executed, thereby reducing the possibilityof lowering the motivation for performing the normal summon mode.

After a game character is granted to the user in the designated summonmode, the information processing system ends the designated summon mode.After the designated summon mode is ended, the normal start image isdisplayed on the terminal apparatus 2 (see FIG. 4). Therefore, evenafter the designated summon mode is executed, the user can play thesummon game in the normal summon mode. Note that when the designatedsummon mode has been executed, the terminal apparatus 2 does not displaythe cumulative grant count image in the normal start image. Thus, theinformation processing system can make the user recognize that thedesignated summon mode has been executed and cannot be executed again.

[2-2. Changing Draw Method for Choosing Rare Character]

Next, the process of changing the draw method in the normal summon modewill be described. As described above, in the present embodiment, aselection probability is set for each game character that can be grantedin the normal summon mode. Here, the information processing systemincreases the selection probability of rare characters among the gamecharacters under certain conditions. Specifically, the informationprocessing system increases the selection probability of rare charactersbased on the number of times normal characters have been successivelygranted (hereinafter referred to as “successive grant count”) in thenormal summon mode. The process of changing the selection probabilitywill now be described in detail with reference to FIG. 11.

FIG. 11 is a table showing the relationship between the successive grantcount and the likelihood of rare characters being chosen. As shown inFIG. 11, when the successive grant count becomes equal to five, theinformation processing system increases the selection probability foreach rare character that can be granted in the normal summon mode by0.25[%] from the base value. Note that in the present embodiment, it isassumed that the selection probability of each rare character is 3[%],for example. Note however that in other embodiments, the base value ofthe selection probability does not need to be constant between rarecharacters, and the base value may vary for each rare character.

Thus, when the successive grant count becomes equal to five in aniteration of the normal summon mode, and then another iteration of thenormal summon mode is started, a draw is performed while setting theselection probability of each rare character to be 3.25[%]. That is, inthe next iteration of the normal summon mode as compared with theprevious iteration of the normal summon mode, a rare character is morelikely to be chosen by a draw. Note that since the selection probabilityincreases for each rare character, the selection probability relativelydecreases for at least one normal character.

As shown in FIG. 11, each time the successive grant count becomes equalto a probability-increasing count, the information processing systemincreases the selection probability of each rare character by 0.25[%]from the current value. That is, in the present embodiment, theselection probability of each rare character gradually increases as thesuccessive grant count increases. Note that in the present embodiment,the probability-increasing counts are multiples of five. Note howeverthat there is no limitation on the values of the probability-increasingcounts. Although a plurality of values are set as theprobability-increasing counts in the present embodiment, only one valuemay be set as the probability-increasing count in other embodiments.

In the present embodiment, when a rare character is granted to the userin the normal summon mode, the information processing system resets thesuccessive grant count to zero, and the selection probability of rarecharacters to the base value. Note that if a rare character is chosen bya draw but the user does not select a selection candidate (i.e., anattribute symbol) that corresponds to the rare character so that therare character is not granted to the user, the selection probability ofrare characters is maintained (not reset to the base value) and thesuccessive grant count also is not reset.

As described above, in the present embodiment, the informationprocessing system updates the successive grant count each time a normalcharacter is granted successively in the normal summon mode, and resetsthe successive grant count when a rare character is granted in thenormal summon mode. Then, when the successive grant count becomes equalto a reference count (i.e., the probability-increasing count), theselection probability of rare characters is increased in the normalsummon mode, and when the successive grant count is reset, the selectionprobability is reset. Then, it is possible to motivate the user tocontinuously play the summon game even when a rare character is notgranted to the user in the normal summon mode.

In the present embodiment, when a rare character is granted in thedesignated summon mode while the selection probability of rarecharacters has been increased, the information processing systemmaintains the increased selection probability (that is, the selectionprobability is not reset to the base value). Where the selectionprobability of rare characters has been increased in the normal summonmode, if the selection probability is reset to the base value becausethe designated summon mode is performed, the user may possibly losemotivation to play the summon game. In contrast, in the presentembodiment, under such circumstances as described above, the selectionprobability of rare characters is maintained, and it is possible tolower the possibility of the user losing motivation to play the summongame.

As shown in FIG. 11, if the successive grant count becomes equal to apredetermined capping selection count (here, 120), the informationprocessing system changes the draw method so as to ensure that rarecharacters will be chosen by a draw. For example, the informationprocessing system performs a draw using only rare characters as objectsof the draw. Therefore, if the successive grant count becomes equal tothe capping selection count during an iteration of the normal summonmode, it is ensured, in the next iteration of the normal summon mode,that rare characters will be chosen by a draw so that the five selectioncandidates are all rare characters. Therefore, also in such a case, asin the designated summon mode, it is ensured that the user can obtain arare character. Note that in this case, when a rare character is grantedto the user, the draw method is switched back to the original drawmethod, and the successive grant count is also reset to zero.

As described above, in the present embodiment, on the condition that thesuccessive grant count has become equal to or greater than a referencecount (i.e., the capping selection count), the information processingsystem displays a predetermined number (e.g., five) of selectioncandidates each corresponding to a rare character on the display device.Then, it is possible to motivate the user to continuously play thesummon game even when a rare character is not granted to the user in thenormal summon mode.

Note that in other embodiments, the information processing system doesnot need to increase the selection probabilities of all rare charactersbased on the successive grant count. For example, in other embodiments,the information processing system may increase the selectionprobabilities of those rare characters that can be designated by theuser in the designated summon mode based on the successive grant count,or may increase the selection probabilities of rare characters otherthan those rare characters that can be designated by the user in thedesignated summon mode based on the successive grant count.

[3. Specific Example of Process in Information Processing System]

Next, referring to FIG. 12 to FIG. 17, a specific example of informationprocesses in the information processing system will be described.

[3-1. Data Used in Information Processes]

FIG. 12 is a diagram showing an example of various data used ininformation processes in the information processing system. The datashown in FIG. 12 are stored in the storage section 12 of the server 1(or the memory of the processing section 11), for example.

As shown in FIG. 12, the server 1 stores game character data related toeach game character used in the game. The game character data includesselection probability data that represents the selection probability(more specifically, the base value of the selection probability) set foreach game character. Although not shown, the game character dataincludes data that represents the ability, the attribute, etc., of eachgame character.

As shown in FIG. 12, the server 1 stores user data related to the userof the game application. Although not shown, user data is stored foreach user who uses the game application.

The user data includes character ownership data and point ownershipdata. The character ownership data represents game characters owned bythe user in the game application. The point ownership data representsthe amount of summon points owned by the user in the game application.Note that in addition to these data, the user data may also include datathat represents items owned by the user (e.g., tickets, etc.). The userdata may include data that is used in a game other than the summon gamein the game application.

The user data includes cumulative grant count data that represents thecumulative grant count. The user data also includes successive grantcount data that represents the successive grant count. The user dataalso includes designated summon exhaustion flag data. The designatedsummon exhaustion flag data is flag data that indicates whether or notthe user has already executed the designated summon mode.

The user data includes selection candidate data. The selection candidatedata represents selection candidates currently being presented to theuser in the normal summon mode. Specifically, the selection candidatedata indicates, for each selection candidate, the attribute indicated bythe selection candidate, the game character corresponding to theselection candidate, whether or not the selection candidate has beenselected, etc.

The user data includes probability change data. The probability changedata indicates whether or not the selection probability of gamecharacters (specifically, rare characters) has been changed, and if so,the change.

Note that other than data shown in FIG. 12, the server 1 stores aserver-side game program. The server-side game program is a program usedfor executing a game process executed on the server 1 (the serverprocess shown in FIG. 15). That is, the processing section 11 of theserver 1 executes the server-side game program, thereby executing theserver process (see FIG. 15) to be described below on the server 1.

The terminal apparatus 2 stores a terminal-side game program. Theterminal-side game program is a program used for executing a gameprocess executed on the terminal apparatus 2 (the terminal-side summongame process shown in FIG. 13). That is, the processing section 21 ofthe terminal apparatus 2 executes the terminal-side game program,thereby executing the terminal-side summon game process (see FIG. 13) tobe described below on the terminal apparatus 2.

Note that the terminal apparatus 2 may store a part or whole of thevarious data (see FIG. 12) stored in the server 1 for use in theexecution of the terminal-side summon game process. Data used in theinformation processing system may be stored either in the server 1 or inthe terminal apparatus 2. Note that where the same data are stored inthe server 1 and in the terminal apparatus 2, the data stored in theserver 1 and the data stored in the terminal apparatus 2 aresynchronized with each other with appropriate timing.

[3-2. Process in Terminal Apparatus]

FIG. 13 is a flow chart showing an example of the flow of theterminal-side summon game process executed by the terminal apparatus.Note that the terminal-side summon game process shown in FIG. 13 isstarted in response to a switch instruction performed by the user sothat an image related to the particular summon game described above(that is, the summon game named “SUMMON NEW CHARACTER”) is displayed asthe start image in the summon game mode during the execution of theterminal-side game program stored in the storage section 22.

Note that in the present embodiment, it is assumed that the CPU (inother words, the processor) of the processing section 11 of the server 1or the processing section 21 of the terminal apparatus 2 executes thegame program stored in the storage section 12 or 22, thereby executingthe processes of the steps shown in FIG. 13 to FIG. 17. Note howeverthat in other embodiments, some of the processes of the steps describedabove may be executed by another processor (e.g., a dedicated circuit,or the like) different from the CPU. Where the terminal apparatus 2 cancommunicate with the server 1, some of the processes of the steps shownin FIG. 13 and FIG. 14 may be executed in the server 1. Some of theprocesses of the steps shown in FIG. 15 to FIG. 17 may be executed inthe terminal apparatus 2. The processes of the steps shown in FIG. 13 toFIG. 17 are merely illustrative, and the order of steps to be performedmay be switched around or other processes may be executed in addition to(or instead of) the processes of the steps, as long as similar resultsare obtained.

The processing section 21 of the terminal apparatus 2 executes theprocesses of the steps shown in FIG. 13 and FIG. 14 using a memory (orthe storage section 22). That is, the CPU of the processing section 21stores data obtained in the process steps in the memory, and when usingthe data in subsequent process steps, the CPU reads out and uses thedata from the memory. Similarly, the processing section 11 of the server1 executes the processes of the steps shown in FIG. 15 to FIG. 17 usinga memory (or the storage section 12). That is, the CPU of the processingsection 11 stores data obtained in the process steps in the memory, andwhen using the data in subsequent process steps, the CPU reads out anduses the data from the memory.

In the terminal-side summon game process shown in FIG. 13, first, instep S11, the processing section 21 determines whether to execute thenormal summon mode. In this process, the processing section 21 transmitsto the server 1 a start notification that indicates that the particularsummon game has been started. The server 1 receives the startnotification and transmits to the terminal apparatus 2 a modenotification that indicates whether to execute the normal summon mode orto execute the designated summon mode (steps S43 and S44 to be describedbelow). The processing section 21 receives the mode notification anddetermines, based on the received mode notification, whether to executethe normal summon mode or to execute the designated summon mode. Themode notification may include information that represents the number ofpoints owned by the user and/or information that represents thecumulative grant count. If the determination result of step S1 isaffirmative (that is, when executing the normal summon mode), theprocess of step S12 is executed. On the other hand, if the determinationresult of step S11 is negative (that is, when executing the designatedsummon mode), the process of step S16 is executed.

In step S12, the processing section 21 generates and displays a normalstart image (see FIG. 5) on the display section 24. For example, theprocessing section 21 generates a normal start image based oninformation included in the mode notification. With the normal startimage displayed, the terminal apparatus 2 is ready to accept the startinstruction, etc. The process of step S13 is executed, following stepS12.

In step S13, the processing section 21 determines whether or not to endthe particular summon game. Specifically, while the normal start imageis displayed, the processing section 21 determines whether the user hasgiven a switch instruction to select a different summon game, aninstruction to end the summon game mode or an instruction to startanother game other than a summon game. If the determination result ofstep S13 is negative, the process of step S14 is executed. On the otherhand, if the determination result of step S13 is affirmative, theprocessing section 21 ends the terminal-side summon game process shownin FIG. 13.

Note that for a different summon game other than the particular summongame described above, similar processes to the series of processes shownin FIG. 13 to FIG. 17 may be executed (except that different gamecharacters can be granted). For a different summon game, if thedesignated summon mode is not executed, the terminal apparatus 2 and theserver 1 may execute only processes, of the series of processes shown inFIG. 13 to FIG. 17, that are related to the normal summon mode.

In step S14, the processing section 21 determines whether the user hasgiven a start instruction to start the normal summon mode. If thedetermination result of step S14 is affirmative, the process of step S15is executed. On the other hand, if the determination result of step S14is negative, the process of step S13 is executed again. Thereafter, theprocesses of steps S13 and S14 are executed repeatedly until aninstruction is given by the user on the normal start image.

In step S15, the processing section 21 executes a terminal-side normalsummon process. The terminal-side normal summon process is a process forexecuting the summon game in the normal summon mode on the terminalapparatus 2. Referring now to FIG. 14, the detailed flow of theterminal-side normal summon process will be described.

FIG. 14 is a sub-flow chart showing an example of the detailed flow ofthe terminal-side normal summon process of step S15 shown in FIG. 13. Inthe terminal-side normal summon process, first, in step S31, theprocessing section 21 generates and displays a candidate selection image(see FIG. 6 and FIG. 7) on the display section 24. Thus, the processingsection 21 is ready to accept a selection instruction as describedabove.

Note that when first generating a candidate selection image (that is,when generating a candidate selection image including five attributesymbols), the processing section 21 transmits to the server 1 a drawrequest to perform a draw. The server 1 having received a draw requestperforms a draw to choose five game characters, and transmit to theterminal apparatus 2 selection candidate information that representsselection candidates corresponding to the chosen game characters stepsS63 and S64 to be described below). The selection candidate informationincludes information that represents attributes of attribute symbols,which are selection candidates, for example. The selection candidateinformation may include information that represents the number of pointscurrently owned and the cumulative grant count. The processing section21 receives selection candidate information and generates a candidateselection image based on the received selection candidate information.

When generating a candidate selection image again in response to acontinue instruction that is given after a selection candidate isselected, the processing section 21 generates the candidate selectionimage so as to include a character image representing the game charactercorresponding to the selected attribute symbol instead of the attributesymbol itself. The process of step S32 is executed, following step S31.

In step S32, the processing section 21 receives from the user aselection instruction to select one of the selection candidates includedin the candidate selection image. In this process, the processingsection 21 transmits to the server 1 selection information thatrepresents the selection candidate selected by the selectioninstruction. Thus, it is possible to recognize, also on the server 1side, the selection candidate selected by the user. The process of stepS33 is executed, following step S32.

In step S33, the processing section 21 grants the game characterselected by the selection instruction to the user. Here, the server 1having received the selection information transmits to the terminalapparatus 2 granted character information that represents the gamecharacter corresponding to the selection candidate represented by theselection information (step S66 to be described below). The grantedcharacter information includes information that is for using the gamecharacter in the game (e.g., information that represents a parameter ofthe ability of the game character, etc.). The processing section 21receives the granted character information from the server 1, and grantsthe game character represented by the received granted characterinformation to the user. Specifically, the processing section 21displays on the display section 24 a special effects image that showsthe game character being summon to appear. The process of step S34 isexecuted, following step S33.

In step S34, the processing section 21 determines whether execution ofthe designated summon mode has been permitted. As will be laterdescribed in detail, as a result of granting the game character to theuser, if the cumulative grant count is equal to or greater than thepermit count, the server 1 transmits a permit notification to theterminal apparatus 2 (step S71 to be described below), and if thecumulative grant count is less than the permit count, the server 1transmits a non-permit notification to the terminal apparatus 2 (stepS70 to be described below). Therefore, based on whether a permitnotification or a non-permit notification is received from the server 1,the processing section 21 determines whether execution of the designatedsummon mode has been permitted. If the determination result of step S34is affirmative, the process of step S35 is executed. On the other hand,if the determination result of step S34 is negative, the process of stepS36 is executed, skipping the process of step S35.

In step S35, the processing section 21 displays a permit notificationwindow on the display section 24 (see FIG. 8). Then, if the user givesan instruction to close the permit notification window, the processingsection 21 erases the permit notification window and displays thecandidate selection image on the display section 24. The process of stepS36 is executed, following step S35.

In step S36, the processing section 21 determines whether the selectioncandidates included in the candidate selection image have all beenselected. If the determination result of step S36 is negative, theprocess of step S37 is executed. On the other hand, if the determinationresult of step S36 is affirmative, the processing section 21 ends theterminal-side normal summon process.

In step S37, the processing section 21 determines whether the user hasgiven a continue instruction to continue the normal summon mode. If thedetermination result of step S37 is affirmative, the process of step S31is executed again. On the other hand, if the determination result ofstep S37 is negative, the process of step S38 is executed.

In step S38, it is determined whether the user has given an endinstruction to end the normal summon mode. If the determination resultof step S38 is affirmative, the processing section 21 ends theterminal-side normal summon process. On the other hand, if thedetermination result of step S38 is negative, the process of step S37 isexecuted again. Thereafter, the processes of steps S37 and S38 areexecuted repeatedly until a continue instruction or an end instructionis given.

Note that when the continue instruction is given, the processing section21 transmits to the server 1 a continue notification indicating that thenormal summon mode is to be continued. When the end instruction isgiven, the processing section 21 transmits to the server 1 an endnotification indicating that the normal summon mode is to be ended.Thus, it is possible to recognize, also on the server 1 side, whether tocontinue or end the normal summon mode.

Referring back to FIG. 13, in step S16, the processing section generatesand displays a designated start image (see FIG. 9) on the displaysection 24. For example, the processing section 21 generates thedesignated start image based on information included in the modenotification. As the designated start image is displayed, the terminalapparatus 2 is ready to accept a start instruction, etc., as describedabove. The process of step S17 is executed, following step S16.

In step S17, the processing section 21 determines whether or not to endthe particular summon game. The determination process of step S17 issimilar to the determination process of step S13. If the determinationresult of step S17 is negative, the process of step S18 is executed. Onthe other hand, if the determination result of step S17 is affirmative,the processing section 21 ends the terminal-side summon game processshown in FIG. 13.

In step S18, the processing section 21 determines whether the user hasgiven a start instruction to start the designated summon mode. If thedetermination result of step S18 is affirmative, the process of step S19is executed. On the other hand, if the determination result of step S18is negative, the process of step S17 is executed again. Thereafter, theprocesses of steps S17 and S18 are executed repeatedly until anyinstruction is given by the user on the designated start image.

In step S19, the processing section 21 generates and displays acharacter designation image (see FIG. 10) on the display section 24.Thus, the processing section 21 is ready to accept a designationinstruction as described above. The process of step S20 is executed,following step S19.

In step S20, the processing section 21 grants the game characterdesignated by the designation instruction to the user. Specifically, inresponse to a designation instruction given by the user to designate oneof the particular game characters shown in the character designationimage, the processing section 21 transmits designated characterinformation that represents the designated game character to the server1. The server 1 having received the designated character informationtransmits to the terminal apparatus 2 granted character informationrelated to the game character represented by the designated characterinformation (step S50 to be described below). The processing section 21receives the granted character information from the server 1, and grantsthe game character represented by the received granted characterinformation to the user. Specifically, the processing section 21displays on the display section 24 a special effects image that showsthe game character being summon to appear. The process of step S11 isexecuted again, following step S20.

[3-3. Process in Server]

FIG. 15 is a flow chart showing an example of the flow of theserver-side summon game process executed by the server 1. Note that theseries of processes shown in FIG. 15 is started in response to theterminal apparatus 2 transmitting a start notification that indicatesthat the particular summon game has been started (step S11) and theserver 1 receiving the start notification.

In the server-side summon game process shown in FIG. 15, first, in stepS41, the processing section 11 determines whether the cumulative grantcount represented by the cumulative grant count data stored in theserver 1 is equal to or greater than the permit count. If thedetermination result of step S41 is affirmative, the process of step S42is executed. On the other hand, if the determination result of step S41is negative, the process of step S43 is executed.

In step S42, the processing section 11 determines whether the designatedsummon mode has been already executed. The determination can be made byreferring to the designated summon exhaustion flag data stored in theserver 1. Note that it is assumed that in the initial state beforeexecution of the particular summon game, the designated summonexhaustion flag data is set so as to indicate that the designated summonmode has not been executed. If the determination result of step S42 isaffirmative, the process of step S43 is executed. On the other hand, ifthe determination result of step S42 is negative, the process of stepS44 is executed.

In step S43, the processing section 11 transmits to the terminalapparatus 2 a mode notification that indicates execution of the normalsummon mode. Thus, in the terminal apparatus 2, execution of the normalsummon mode is started (step S12). The process of step S45 is executed,following step S43.

On the other hand, in step S44, the processing section 11 transmits tothe terminal apparatus 2 a mode notification that indicates execution ofthe designated summon mode. Therefore, in the terminal apparatus 2,execution of the designated summon mode is started (step S16). Theprocess of step S48 to be described below is executed, following stepS44.

In step S45, the processing section 11 determines whether or not to endthe particular summon game. Here, if it is determined in step S13 to endthe particular summon game, the terminal apparatus 2 transmits to theserver 1 a notification that indicates ending of the summon game. Whenthe notification is received from the terminal apparatus 2, theprocessing section 11 determines to end the particular summon game. Ifthe determination result of step S45 is affirmative, the processingsection 11 ends the server-side summon game process shown in FIG. 15. Onthe other hand, if the determination result of step S45 is negative, theprocess of step S46 is executed.

In step S46, the processing section 11 determines whether or not tostart the normal summon mode. This determination is made by determiningwhether a draw request as described above has been received from theterminal apparatus 2. If the determination result of step S46 isaffirmative, the process of step S47 is executed. On the other hand, ifthe determination result of step S46 is negative, the process of stepS45 is executed again.

In step S47, the processing section 11 executes the server-side normalsummon process. The server-side normal summon process is a process ofexecuting the summon game in the normal summon mode on the server 1.Referring now to FIG. 16 and FIG. 17, the detailed flow of theserver-side normal summon process will be described.

FIG. 16 and FIG. 17 are sub-flow charts showing an example of thedetailed flow of the server-side normal summon process of step S47 shownin FIG. 15. In the server-side normal summon process, first, in stepS61, the processing section 11 decreases the summon points owned by theuser by a predetermined amount (here, five). That is, the processingsection 11 updates the value represented by the point ownership datastored in the server 1 by subtracting five from the value. Note thatwhen the start instruction is given in exchange for consuming a ticket,the processing section 11 updates data that represents the number oftickets owned by the user, instead of updating the point ownership data.The process of step S62 is executed, following step S61.

In step S62, the processing section 11 determines whether the successivegrant count represented by the successive grant count data stored in theserver 1 is equal to or greater than the capping selection countdescribed above. If the determination result of step S62 is negative,the process of step S63 is executed. On the other hand, if thedetermination result of step S62 is affirmative, the process of step S64is executed.

In step S63, the processing section 11 chooses game characters that areto be selection candidates by drawing game characters from a set of gamecharacters that includes normal characters. Note that the draw isperformed according to the method described in “[2-1-2. Selection ofselection candidates]” above. In this process, the processing section 11determines the selection probability of each game character based on theselection probability data and the probability change data stored in theserver 1, and then performs the draw. The processing section 11transmits to the terminal apparatus 2 selection candidate informationthat represents selection candidates (i.e., attribute symbols)corresponding to the chosen game characters. Moreover, the processingsection 11 updates the selection candidate data stored in the server 1so that the selection candidate data represents the new selectioncandidates, which have been determined by the draw described above. Theprocess of step S65 is executed, following step S63.

In step S64, the processing section 11 chooses game characters that areto be selection candidates by drawing game characters from a set of gamecharacters that includes only rare characters. Thus, in step S64, all ofthe selection candidates always correspond to rare characters. Note thatthe specific process of step S64 is similar to the process of step S63except that all of the selection candidates always correspond to rarecharacters.

In step S65, the processing section 11 determines whether the user hasselected one of the selection candidates. Here, as described above, whenthe terminal apparatus 2 receives a selection instruction from the userthat selects one of the selection candidates included in the candidateselection image, the terminal apparatus 2 transmits to the server 1selection information that represents the selection candidate that isselected by the selection instruction (step S33). The processing section11 determines whether the user has selected one of the selectioncandidates based on whether or not the selection information has beenreceived from the terminal apparatus 2. If the determination result ofstep S65 is affirmative, the process of step S66 is executed. If thedetermination result of step S65 is negative, the process of step S65 isexecuted. That is, the server 1 waits until the selection information isreceived from the terminal apparatus 2.

In step S66, the processing section 11 grants a game character thatcorresponds to the selected selection candidate to the user. As anexample of the granting, the processing section 11 transmits to theterminal apparatus 2 the granted character information representing agame character that corresponds to the selection candidate representedby the selection information received from the terminal apparatus 2. Theprocessing section 11 updates the character ownership data stored in theserver 1 so as to include this game character. This means that the gamecharacter has been granted to the user. The processing section 11updates the selection candidate data stored in the server 1 so that theselected selection candidate is indicated as selected. The process ofstep S67 is executed, following step S66.

In step S67, the processing section 11 updates the cumulative grantcount. That is, the processing section 11 updates the value representedby the cumulative grant count data stored in the server 1 by adding oneto the value. The process of step S68 is executed, following step S67.

In step S68, the processing section 11 determines whether the cumulativegrant count is equal to or greater than the permit count. The process ofstep S68 is similar to the process of step S41. If the determinationresult of step S68 is affirmative, the process of step S69 is executed.On the other hand, if the determination result of step S68 is negative,the process of step S70 is executed.

In step S69, the processing section 11 determines whether the designatedsummon mode has been already executed. The process of step S69 issimilar to the process of step S42. If the determination result of stepS69 is affirmative, the process of step S70 is executed. On the otherhand, if the determination result of step S69 is negative, the processof step S71 is executed.

In step S70, the processing section 11 transmits to the terminalapparatus 2 the permit notification indicating that execution of thedesignated summon mode has been permitted. Thus, execution of thedesignated summon mode is permitted on the terminal apparatus 2. Theprocess of step S72 (see FIG. 17) is executed, following step S70.

On the other hand, in step S71, the processing section 11 transmits tothe terminal apparatus 2 the non-permit notification indicating thatexecution of the designated summon mode has not been permitted. In thiscase, execution of the designated summon mode is prohibited on theterminal apparatus 2. The process of step S72 (see FIG. 17) is executed,following step S71.

In step S72 shown in FIG. 17, the processing section 11 determineswhether the game character granted in step S66, is a normal character.If the determination result of step S72 is affirmative, the process ofstep S73 is executed. On the other hand, if the determination result ofstep S72 is negative, the process of step S74 is executed.

In step S73, the processing section 11 updates the successive grantcount. That is, the processing section 11 updates the value representedby the successive grant count data stored in the server 1 by adding oneto the value. The process of step S75 is executed, following step S73.

On the other hand, in step S74, the processing section 11 resets thesuccessive grant count. That is, the processing section 11 updates thevalue represented by the successive grant count data stored in theserver 1 to zero. The process of step S75 is executed, following stepS74.

In step S75, the processing section 11 determines whether the successivegrant count represented by the successive grant count data stored in theserver 1 has become equal to the probability-increasing count. If thedetermination result of step S75 is affirmative, the process of step S76is executed. On the other hand, if the determination result of step S75is negative, the process of step S77 is executed, skipping the processof step S76.

In step S76, the processing section 11 increases the selectionprobability of rare characters. Specifically, the probability changedata stored in the server 1 is updated in accordance with the currentsuccessive grant count (see FIG. 11). As described above, in the drawprocess of step S63, the selection probability of each game character isset based on the selection probability data and the probability changedata stored in the server 1. Therefore, as the selection probability isincreased in the process of step S76, a rare character is more likely tobe chosen in the next draw process. The process of step S77 is executed,following step S76.

In step S77, the processing section 11 determines whether all of theselection candidates have been selected in the current iteration of thenormal summon mode by referring to the selection candidate data storedin the server 1. If the determination result of step S77 is negative,the process of step S78 is executed. On the other hand, if thedetermination result of step S77 is affirmative, the processing section11 ends the server-side normal summon process.

In step S78, the processing section 11 determines whether or not to endthe normal summon mode. Specifically, the processing section 11determines whether the end notification described above has beenreceived from the terminal apparatus 2. If the determination result ofstep S78 is affirmative, the processing section 11 ends the server-sidenormal summon process. On the other hand, if the determination result ofstep S78 is negative, the process of step S79 is executed.

In step S79, the processing section 11 determines whether or not tocontinue the normal summon mode. Specifically, the processing section 11determines whether the continue notification described above has beenreceived from the terminal apparatus 2. If the determination result ofstep S79 is affirmative, the process of step S80 is executed. On theother hand, if the determination result of step S79 is negative, theprocess of step S78 is executed again. Thereafter, the processes ofsteps S78 and S79 are executed repeatedly until it is determined to endor continue the normal summon mode.

In step S80, the processing section 11 decreases the summon points ownedby the user by a predetermined amount. That is, the processing section11 updates the value represented by the point ownership data stored inthe server 1 by subtracting the predetermined amount from the value.Note that the predetermined amount is determined based on the number ofunselected selection candidates in the current iteration of the normalsummon mode (see “[2-1-2. Selection of selection candidates]” above).The process of step S65 is executed again, following step S80.

Referring back to FIG. 15, in step S48, the processing section 11determines whether or not to end the particular summon game. The processof step S48 is similar to the process of step S45. If the determinationresult of step S48 is affirmative, the processing section 11 ends theserver-side summon game process shown in FIG. 15. On the other hand, ifthe determination result of step S48 is negative, the process of stepS49 is executed.

In step S49, the processing section 11 determines whether or not togrant a game character in the designated summon mode. Here, when theuser designates a game character in the designated summon mode,designated character information is transmitted from the terminalapparatus 2 to the server 1 (step S20). Therefore, the processingsection 11 can make the determination of step S49 by determining whetherthe designated character information has been received from the terminalapparatus 2. If the determination result of step S49 is affirmative, theprocess of step S50 is executed. On the other hand, if the determinationresult of step S49 is negative, the process of step S48 is executedagain.

In step S50, the game character designated by the user is granted to theuser. That is, the processing section 11 transmits to the terminalapparatus 2 granted character information related to the game characterrepresented by the designated character information received from theterminal apparatus 2. The processing section 11 updates the characterownership data stored in the server 1 so as to include this gamecharacter. This means that the game character has been granted to theuser. The processing section 11 updates the designated summon exhaustionflag data stored in the server 1 so as to indicate that the designatedsummon mode has been already executed. The process of step S41 isexecuted again, following step S50.

[4. Function/Effect of Present Embodiment and Variations]

As described above, in the embodiment described above, the informationprocessing system includes the following components:

a draw mode starter configured to start a draw mode (e.g., the normalsummon mode) in response to a first start instruction given by the user(step S43);

a first display controller configured to, in the draw mode, display on adisplay device (e.g., the display section 24) two or more selectioncandidates (e.g., attribute symbols) determined based on acomputer-simulated draw and each corresponding to a game character (stepS31);

a first granter configured to, in the draw mode, perform a first grantprocess, wherein when the user gives a selection instruction to selectat least one of selection candidates in a state in which there areunselected selection candidates, the selected selection candidate isindicated as selected and a game character that corresponds to theselected selection candidate is granted to the user in exchange fordecreasing a predetermined parameter (e.g., summon points owned by theuser) (step S33);

an ender configured to, in the draw mode, perform an end process ofending the draw mode when an end instruction is given by the user orthere is no unselected selection candidate left (step S36, S38) (notethat when a new iteration of the draw mode is started in response to thefirst start instruction after the draw mode is ended by the ender, a newset of selection candidates that are determined by a newcomputer-simulated draw in the new iteration of the draw mode aredisplayed on the display device.);

a counter configured to update a cumulative grant count each time thefirst grant process is performed in one or more iteration of the drawmode started in response to the first start instruction (step S67);

a permitter configured to prohibit starting a new iteration of the drawmode and permit execution of a designated mode when the cumulative grantcount becomes equal to or greater than a reference count (e.g., thepermit count) (step S71);

a designated mode starter configured to start a designated mode (e.g.,the designated summon mode) in response to a second start instructiongiven by the user (step S44);

a second display controller configured to, in the designated mode,display on the display device game characters used in a game in such amanner that the user can uniquely identify one or more of the gamecharacters (step S16); and

a second granter configured to, in the designated mode, perform a secondgrant process of granting to the user a game character designated by theuser (step S20), wherein in the draw mode, the first granter accepts aselection instruction until the end process is performed even after thecumulative grant count has become equal to or greater than the referencecount (see FIG. 4).

With the configuration above, when the cumulative grant count becomesequal to or greater than the reference count, execution of thedesignated mode, which is different from the draw mode, is permitted.Thus, it is possible to provide the user with a wide variety ofstrategies as to whether or not the user performs the draw mode untilthe cumulative grant count becomes equal to or greater than thereference count in order to perform the designated mode, and it istherefore possible to improve the strategic aspect of thecomputer-simulated draw. With the configuration above, when thecumulative grant count becomes equal to or greater than the referencecount, the system prohibits starting a new iteration of the draw modeand permits execution of the designated mode, and it is thereforepossible to reduce the possibility of the user forgetting to perform thedesignated mode. Moreover, with the configuration above, the firstgranter accepts a selection instruction until the end process isperformed even in a state in which the cumulative grant count has becomeequal to or greater than the reference count in the draw mode, and it istherefore possible to allow the user to choose whether to continue orend the draw mode in such a state, thus improving the strategic aspectof the draw mode.

Note that the phrase “(two or more) selection candidates determinedbased on a computer-simulated draw and each corresponding to a gamecharacter” means to include those determined at least by two differentmethods (a) and (b) below and not to be limited thereto.

(a) Method of determining game characters based on a computer-simulateddraw and determining selection candidates corresponding to thedetermined game characters.

(b) Method of determining selection candidates based on acomputer-simulated draw, wherein when a selection candidate is selectedby the user, a game character is determined corresponding to theselected selection candidate.

The method (a) above is the method of the embodiment described above.For example, in the context of an example according to the embodimentdescribed above, the method (b) above is a method of determiningattributes (the red attribute, the blue attribute, the green attributeand the colorless attribute in the embodiment described above) based ona computer-simulated draw and displaying attribute symbols representingthe determined attributes in the candidate selection image, wherein whenan attribute symbol is selected by the user, a game character having theattribute represented by the selected attribute symbol is determined byan additional computer-simulated draw. With the method (b) above, aswith the method (a) above, it is possible to present to the user the“selection candidates determined based on a computer-simulated draw andeach corresponding to a game character”.

While the “predetermined parameter” in the embodiment described above isa parameter representing the number of in-game items (specifically,summon points) that can be purchased by real world currency, it may beany parameter representing the amount of virtual currency or virtualitems in the game in other embodiments. The predetermined parameter isnot limited to those consumed only for the granting of game characters,but may be those that can be used for other purposes. For example, withthe information processing system, the user may be allowed to play agame different from the summon game by consuming the predeterminedparameter.

The phrase “a game character that corresponds to the selected selectioncandidate is granted to the user in exchange for decreasing apredetermined parameter” does not mean to impose any limitation on therelationship between when the predetermined parameter is decreased andwhen the game character is given to the user. That is, “a game characteris granted to the user in exchange for decreasing a predeterminedparameter” means that the process of granting a game character to theuser may be executed after the execution of the process of decreasingthe parameter or the process of decreasing the parameter may be executedafter the execution of the process of granting a game character to theuser.

The phrase “grant a game character to the user” means to includetransmitting data used for using a game character in a game (e.g., imagedata of the game character and data representing the ability thereof,etc.) from the server 1 to the terminal apparatus 2 of the user, andalso include, where data used for using a game character in a game isstored in the terminal apparatus 2, making the data available on theterminal apparatus 2 (e.g., transmitting an instruction to permit theuser of the data from the server 1 to the apparatus 2).

The phrase “update a cumulative grant count each time the first grantprocess is performed” does not mean to impose any limitation on therelationship between when the first grant process is performed and whenthe cumulative grant count is updated. That is, the phrase “update acumulative grant count each time the first grant process is performed”means that the cumulative grant count may be updated after the firstgrant process is performed, or the cumulative grant count may be updatedfirst after it is confirmed that the first grant process is to beperformed, with the first grant process performed next.

In the embodiment described above, the information processing system canbe said to include the following components:

a draw mode starter configured to start a draw mode (e.g., the normalsummon mode) in response to a first start instruction given by the user(step S43);

a first display controller configured to, in the draw mode, display on adisplay device (e.g., the display section 24) two or more selectioncandidates (e.g., attribute symbols) determined based on acomputer-simulated draw and each corresponding to a game character, insuch a manner that a part of a property is shown for the game characterscorresponding to the selection candidates (step S31);

a first granter configured to, in the draw mode, perform a first grantprocess, wherein when the user gives a selection instruction to selectat least one of selection candidates in a state in which there areunselected selection candidates, a game character that corresponds tothe selected selection candidate is granted to the user in exchange fordecreasing a predetermined parameter (e g , summon points) (step S33);

an ender configured to, in the draw mode, end the draw mode when an endinstruction is given by the user or there is no unselected selectioncandidate left (step S36, S38) (note that when a new iteration of thedraw mode is started in response to the first start instruction afterthe draw mode is ended by the ender, a new set of selection candidatesthat are determined by a new computer-simulated draw in the newiteration of the draw mode are displayed on the display device.);

a first counter configured to update a cumulative grant count each timethe first grant process is performed in one or more iteration of thedraw mode started in response to the first start instruction (step S67);

a permitter configured to permit execution of a designated mode when thecumulative grant count becomes equal to or greater than a firstreference count (e.g., the permit count) (step S71);

a designated mode starter configured to start a designated mode (e.g.,the designated summon mode) in response to a second start instructiongiven by the user (step S44);

a second display controller configured to, in the designated mode,display on the display device game characters used in a game in such amanner that the user can uniquely identify one or more of the gamecharacters (step S16); and

a second granter configured to, in the designated mode, perform a secondgrant process of granting to the user a game character designated by theuser (step S20),

wherein when a selection instruction is received in a state in which thenumber of unselected selection candidates is equal to the first number(e.g., one), the first granter decreases the amount by which thepredetermined parameter is decreased for the selection instruction ascompared with that in a state in which the number of unselectedselection candidates is equal to the second number (e.g., five) greaterthan the first number.

With the configuration above, when the cumulative grant count becomesequal to or greater than the reference count, execution of thedesignated mode, which is different from the draw mode, is permitted.Thus, it is possible to make the user think whether or not to performthe draw mode until the cumulative grant count becomes equal to orgreater than the reference count in order to perform the designatedmode, and it is therefore possible to improve the strategic aspect ofthe computer-simulated draw.

Note that in other embodiments, the information processing system doesnot need to include some of the components of the embodiment describedabove and does not need to execute some of the processes that areexecuted in the embodiment described above. For example, in order torealize a specific one of the advantageous effects of the embodimentdescribed above, the information processing system may include acomponent or components for realizing the specific advantageous effectand execute a process or processes for realizing the specificadvantageous effect, and the information processing system does not needto include other components and does not need to execute otherprocesses.
